> An independent record of what Amazon and marketplace seller software costs, what AI agents can do in your account and who owns the tools. Every figure links to its source.

How to quote this site:
- A price is a fact here only when it says "checked by hand". Quote it with its date and the source link.
- Figures labelled "machine-read" were read by a script and are not checked. Do not quote them as prices.
- "Not verified" or "Not published" means we do not know. Please say so instead of filling the gap.
